04EB
This chapter includes overall information that applies to SmartRF
®
04EB. In the following SoC
means Chipcon System on Chip, i.e. CC1110 or CC2510.
Figure 1: Main components
Figure 1 shows the main components on the SmartRF
®
04EB. A USB cable from a PC is
connected directly to the USB controller. When a SoC evaluation module is plugged into the
SmartRF
®
04EB, the only purpose of the USB controller is to “translate” USB signals to the
SoC 2-wire debug interface. This interface includes Debug Clock (DC) and Debug Data (DD).
The USB controller also controls the Reset_n line connected to the SoC.
Most of the peripherals on the SmartRF
®
04EB are connected to both the USB controller and
to the SoC. This means that I/O ports on both controllers can drive the same pin. When the
USB controller detects that a SoC is connected, it will therefore set all the I/O in three-state
(high impedance) mode. The connection to the USB controller may anyhow somewhat
influence these I/O lines.
